No, it'll come in AWD as well and that's what counts for me here in the Alps.
For anybody who's asking why is BMW doing this, the answer is packaging. So it makes sense for smaller cars as the new 1 sedan and hatch. The transversally mounted engine leaves more space to be used for the cabin. That's why the side view of the previous and current 1 series hatch (longitudinally mounted engine) is so different to other hatches and that's why the new A-class MB (transversally mounted engine) is so cute (to many, not to me).
